OGD distance sensors in application ifm dependably measures distance with millimetre precision
ifm electronic has launched a new generation of OGD optical distance sensors which reliably measure distances up to 2 m with an accuracy of one millimetre , even with fast-moving , reflective , multicoloured and other challenging targets .
Like the existing very successful family of OGD sensors , the new models use PMD time-of-flight technology , delivering superior performance to conventional laser and red-light sensors . Unlike their predecessors , however , the new models allow users to choose from three operating modes optimised for range , precision and frequency . This means fewer OGD sensor types are needed to cover the full range of applications .
Because they use PMD technology , all OGD sensors offer excellent reflection resistance and background suppression , making them an ideal choice in critical and demanding applications . In addition , their range is angle and colour independent , allowing them to operate reliably even 50 FDPP - www . fdpp . co . uk

OGD distance sensors
with challenging targets such as reflective metal surfaces . In addition to distance , the new sensors simultaneously measure target reflectivity , providing additional information that can , for example , be used for product sorting .
The new OGD sensors are available in heavy-duty versions with stainless steel housings and light-duty versions with plastic housings . Both versions can be supplied with either two transistor switching outputs or one switching and one analogue output .
The outputs can be configured to operate based on range or reflectivity . In addition , all types have an IO-Link interface which provides full access to range and reflectivity measurements .
An integral display shows the current measured value and can be configured to change colour to indicate an out-oftolerance or alarm condition . The display can also be used to aid in configuring the sensors , in conjunction with three operating buttons built into the device . Alternatively , configuration can be carried out via the IO-Link interface .
